Figure 1

ECG strip demonstrating timing of image acquisition. PTAS CTA is shown with radiation exposure peak at 100% of the reference tube current (red arrow, “Range” settings) at 300–400 msec and a “plateau” (green arrow, “Scan” settings) with 20% of the reference tube current to capture additional phases at mid and late systole/early diastole.
